Abstract
Un système de filtration d'eau est également décrit. Le système de filtration d'eau comprend un récipient de filtration de milieu régénératif, une conduite de filtrat, une conduite d'alimentation, une conduite de recirculation, une conduite de gaz et au moins une pompe. L'invention concerne un procédé de filtrage d'eau dans un système comprenant un filtre de milieu régénératif. Le procédé consiste à faire fonctionner le système dans un mode de filtration, à faire fonctionner le système dans un mode de nettoyage en réponse à une mesure de pression différentielle à travers le filtre de milieu régénératif, à faire fonctionner le système dans un mode d'aération, faire fonctionner le système dans un mode de pré-filtration après le fonctionnement du système dans le mode de nettoyage, faire fonctionner le système dans un mode de drainage, et faire fonctionner le système dans le mode de filtration suivant le mode de drainage. L'invention concerne un dispositif de commande et un support lisible par ordinateur non transitoire sur lequel sont stockés des signaux lisibles par ordinateur qui définissent des instructions qui, en conséquence d'être exécutées par le dispositif de commande, commandent au dispositif de commande d'effectuer un procédé de fonctionnement d'un système de filtration d'eau.
